What is the meaning of "Sunset and Lonely Qi Fei, Autumn waters and sky are the same color"?

Lonely wild ducks and sunset clouds are on the horizon, and the river in autumn is the same color as the sky. This sentence comes from Wang Bo's Preface to Wang Tengting, the famous Farewell. Where does its powerful artistic charm come from? From the colorful beauty it gives readers? The most perfect shaping of a kind of beauty? The first is the beauty of color. Under the setting sun, the sunset glow is dazzling, and the feathers of the emu are dark backlit, so the lonely man and few women are almost a shadow, but the sunset glow can't cover half the sky in the west and is still exposed in the blue sky. The blue sky is not as bright as the sunset glow, but it is brighter than lonely people. They are lonely, sunset and sunset. The colors of solitary fish are mainly green, brown and purple, which are cool colors and complementary colors. The background of sunset glow is clear sky and sapphire, and the colors of sunset glow are complementary. We know that when two complementary colors are adjacent, they can form the strongest contrast, and in effect, they can make both sides reach the maximum brightness. Wang Bo skillfully used this contrast to make the whole design look particularly bright and beautiful. Secondly, dynamic beauty. Lonely people are "flying", clouds are "falling", and only the sky does not move. Although autumn water is quiet, water will not die if it doesn't stop in winter. When the breeze passes, ripples will continue to appear in the autumn water. As soon as the ripples pass, the scenery reflected on the mirror-smooth water surface will be swung open, revealing the underwater scenery: aquatic plants, even fish and shrimp, and so on. This is obviously a beautiful flowing picture. The third is the beauty of truth and falsehood. The blue sky is extremely deep, Xia Hong is slightly lower, and lonely people are even lower. There are three floors here, and the autumn water is below. The water in autumn is quiet. When "autumn water * * * is in the same sky", the picture in the sky is naturally reflected in the water. The so-called "clouds drifting * * *", there are three levels of water. Moreover, the higher the scenery in the sky, the deeper the reflection in the water. This constitutes a contrast between real and virtual scenes. Moreover, when the breeze passes, the autumn water ripples, and the scenery reflected on the smooth mirror-like water surface will be swung away, revealing underwater scenery: aquatic plants, even fish and shrimp. , which constitutes a kind of beauty of virtual reality and the image on the water. The fourth is the beauty of three-dimensional space. "Autumn water * * * sky is the same color", on the horizon, heaven and water? The original two planes on the ground intersect through constant deformation, which conforms to people's visual habits and can make people feel that the whole picture has the realism of three-dimensional space. Not only that, "Autumn Water * * * One Color in the Sky" draws people's attention to the place where water meets the sky, which is the farthest place people can reach. The Sunset and Lonely Qi Fei draws people's attention to the zenith, which is the highest point in people's field of vision. This scene is reflected in the autumn water, which makes the scenery with the highest height have the greatest depth. There are far, high and deep, and the realm is open, giving people a strong three-dimensional sense. The fifth is to arouse people's imagination. In this sentence, birds are alive, but the sky and clouds are lifeless. Here, the latter becomes the background of the former, while the former is an emotional and will activity point of the latter, which makes people think of life and inanimate; The sunset glow is eternal in the sky, and loneliness is just a passer-by, giving people an eternal and short feeling; "Lonely" EMU and "falling" EMU, why is it lonely? Fly there? ..... it's emotional; "Autumn water * * * sky is one color", where is Wang Bo's mood when water and sky meet in the distance? What is the scenery like there? ..... gives people endless reverie loneliness: the meaning of wild ducks!
